Top LINE alternatives for business

Short summaries to help you pick the right platform depending on whether you need messaging, PSTN voice, or developer-level control.

WhatsApp Business

Great for message-first engagement in many markets. Supports official business accounts and templates. Voice calling via the app is possible but not web-first PSTN calling.

Best if you need messaging reach and templated notifications.

Zoom Phone / Microsoft Teams Phone

Full cloud PBX options with PSTN calling, call queues, and contact center integrations. These are strong when you need a complete telephony stack inside your UC environment.

Best if you need integrated PBX and enterprise telephony workflows.

Google Voice / RingCentral

Cloud phone numbers and business calling with good admin controls and integrations. Typically used for US-focused voice and small to mid-market contact centers.

Best for businesses focused on US and international calling with admin controls.

Twilio Programmable Voice

Developer-first PSTN and SIP control with global number provisioning. Ideal when you need full customization, IVR, and call automation. StartACall uses Twilio as the backbone to bridge WebRTC and PSTN.

Best for developers and companies building custom telephony features.

StartACall (Browser VoIP + AI)

StartACall provides browser-based calling to global phone numbers, virtual number management in 190+ countries, AI agents for autonomous calling, and a real-time copilot for live calls. No apps required for agents or customers to pick up phone calls.

Best if you want quick deployment, web-based agents, and AI-assisted calling workflows.

Telegram / Messaging APIs

Strong for bot-based messaging and broadcast. Not designed for PSTN voice out of the box, but useful as part of an omnichannel stack where voice is handled by a separate telephony provider.

Best when messaging automation is the priority and voice is separate.
